English, Painted Post, and Edward C. Morris, Corning, N.Y., assignors to llngersoll-Rand Company, New York, N.Y., a corporation of New Jersey Filed Mar. 22, 1960, Ser. No. 16,7 82 4 Claims. (Cl. 230-188) This invention relates to compresors in general, and more particularly tothe conductance of the intake and exhaust of such compressors.

The commonly known horizontal compressor of the reciprocating piston type is provided with a piping arrangement in which either the exhaust or the intake is connected to the top of the compressor. In plants where multi-unit installations are used the overhead piping of these units is often objectionable especially where the overhead space is restricted.

It is then an object of this invention to provide a compressor having its discharge as well as its intake at the bottom of such compressor.

Another object of this invention is to eliminate the overhead piping for such compressor.

Further objects of this invention will become apparent from the following specification and drawing, in which FIGURE 1 is a longitudinal sectional view of a horizontal piston type compressor,

FIG. 2 is a cross sectional View taken along the line 22 of FIG. 1 looking in the direction of the arrows, and

FIG. 3 is a cross sectional view taken along the line 33 of FIG. 1 looking in the direction of the arrows.

Referring now to the figures for a description of a preferred embodiment o fthis invention, designates a compressor of a commonly known horizontal type including a working cylinder 12 in which a wear sleeve 14 is disposed for the reception of a reciprocating piston 16. An outer cylinder 18 is positioned around the working cylinder 12 cooperating therewith to form a chamber 20 between the cylinders 12 and 18, the function of the chamber 20 to be explained hereinafter.

Arranged in a commonly known pattern around the wear sleeve 14 at the opposite end portions thereof are intake valves 22 and exhaust valves 24 for, respectively, the admittance of fluid into the interior of the working cylinder to be compressed therein by the piston 16, and for the exhaust of fluid from the interior of the working cylinder after such fluid has been compressed therein.

An intake pipe 26 and an exhaust pipe 28 are connected to the bottom of the compressor 10 as shown in FIG. 1, the intake pipe 26 being in communication with the chamber 20 through the intake opening 27 in the outer wall of the outer cylinder 13, and the exhaust pipe 28 being in communication with the chamber 20 through the exhaust opening 29 in the outer wall of the outer cylinder 18. As the fluid from the intake 26 is conducted to the intake valves 22 through the chamber 20, and the discharge from the exhaust valves 24 is conducted to the exhaust 28, also through the chamber 20, the conductance of the discharge fluid is to be separate from the intake fluid.

In order to achieve this, two transverse partitions 30 and 32 are provided in the chamber 20 and longitudinally spaced from each other as shown in FIGS. 1, 2 and 3. The partition 30, see FIG. 2, comprises a closed portion 34 and an open portion 36, the open portion having openings 38 through which the intake fluid flows to both sets of intake valves 22. The partition 32, see FIG. 3, comprises a closed portion 40 and an open portion 42, the open portion having openings 44- through which the exhaust from both sets of exhaust valves 24 flows. It is to be noted that the open portion 36 of the partition 30 is positioned diagonally opposite the open portion 42 of the partition 32, such that the openings 38 in the open portion 36, and the openings 44 in the open portion 42 are arranged in substantially the same pattern as that of, respectively, the intake valves 22 and exhaust valves 24.

As the fluid for the intake valves is to be' conducted separately from the fluid discharged from the exhaust valves, the chamber 20 is divided into two compartments by longitudinal partitions 46 and 48, diagonally opposite each other and positioned longitudinally between the partitions 30 and 32, see FIGS. 2 and 3. In this manner the chamber 20 is divided into two portions, the intake portion 52 and the exhaust portion 54. A number of reinforcement ribs 50 is provided between the outer cylinder 18 and the working cylinder 12 and positioned transversely in the chamber 20, see FIG. 1.

When the compressor 10 is in operation the intake fluid is conducted through the intake pipe 26, intake opening 27 and into the intake portion 52 of the chamber 20 in which the fluid flows through openings 38 in the partition 30 to the intake valves 22. The intake fluid is then prevented from flowing into the exhaust portion 54 of the chamber 20 by the transverse partitions 30* and 32, and by the longitudinal partitions 46 and 48, see FIGS. 1

. and 2. The exhaust fluid is conducted from the exhaust valves 24 into the exhaust portion 54 of the chamber 20 in which the fluid flows through openings 44 in the partition 32, through exhaust openings 29, and into the exhaust pipe 28. The exhaust fluid is prevented from flowing into the intake portion 52 of the chamber 20 by the transverse partitions 30 and 32, and by the longitudinal partitions 46 and 48, see FIGS. 1 and 3.

With the structure shown in FIGS. 1, 2- and 3, the overhead piping of the compressor is eliminated by the arrangement of the aforementioned partitions between the outer cylinder and the working cylinder of the compressor such that the intake of the compressor is conducted into the bottom of the compressor, and the exhaust of the compressor is conducted from the bottom of the compressor.

It is to be understood that the invention is not to be restricted to the details set forth since these may be modified within the scope of the appended claims without departing from the scope and spirit of the invention.
